Ventana System

The Ventana System (Sierras de Ventania) is one of two mountain ranges in Buenos Aires Province, and one of the only two located within the Pampas ecosystem.


Bounded approximately by the Laguna de Guamini at its northwestern end, and the Atlantic Ocean to its southwest, the Ventana System lies on a precambrian base formed around 2.2 billion years ago, and is interspersed with granite, granodiorite, and amphibole deposits.

Characterized by its escarpments, this orography prevented the deposit of significant amounts of loess, and make the area the least propicious to agriculture with the pampas; sunflower fields are common along the foot of the range. Its soils feature a A-AC-C horizonation, not unlike those found along the Appalachian range. Its climate is rather colder and drier than that prevailing in the surrounding Humid Pampas, though the range receives more rainfall than the Semi-arid Pampas, located to the west. Sizable extensions of lacebark pines grow along the range, possibly introduced from Asia.

Peppered by caves and grottoes, the range is relatively modest in height and extension, and exceeds 1000 m (3280 ft) at only six points. These peaks are:

Cura Malal Chico (1000 m)

Cura Malal Grande (1037 m)

Naposta Grande (1108 m)

La Ventana (1184 m)

Destierro Primero (1172 m)

Tres Picos (1239 m)

The region's breezes and mild climate made it of tourist interest since the early part of the 20th century, and its principal early promoter was Ernesto Tornquist, a prominent rancher, banker and developer. The extension of the Buenos Aires Great Southern Railway past the area led to the construction of the Club Hotel de la Ventana, a luxurious casino and hotel, and the outpost of Villa Ventana, a resort community developed by the Sociedad de Companias de Tierras y Hoteles de Sierra de la Ventana. The hotel closed after President Hipolito Yrigoyen's 1918 edict banning gambling, and development of the area's tourism resources remained below their potential in subsequent decades.
